ruby-on-rails - How to include ActionView::Helpers in rails controller?

Question

Following is my code.

class PropertyDetailsController < ApplicationController
  include ActionView::Helpers

  #Action methods.
end

But the above code is throwing following error when I try to run.

Module::DelegationError (ActionView::Helpers::ControllerHelper#action_name delegated to controller.action_name, but controller is nil: 

Any Suggestions.

UPDATE Is that true if we use params and session we cant include ActionView::Helpers
